BIVERTICILLATA -SYMMETRICA 665 



Although the species Penicillium olsoni Bainier and Sartory is accepted 

 as vahd, the possibihty that it represents little more than a coarse, deep 

 variant of P. herquei of the same authors should be recognized. 



Penicillium novae-zeelandiae van Beyma, in Antonie van Leeuwenhoek 6: 



273-275, fig. 7. 1939-1940. 



Van Beyma's description as follows (abstracted): 



Colonies on beer-wort agar in petri dishes after 20 days, large, about 4 cm. in 

 diameter, consisting of numerous black sclerotia arranged in beautiful zones which 

 are soon overgrown by delicate white, wooly mycelium becoming 2-3 mm. in depth, 

 and showing definite funiculose ropes of hvphae; without odor; color in reverse not 

 stated. Conidiophores rarely branched, about 500^ long, .3.0 to 3.3m in diameter with 

 walls conspicuously roughened, producing 3 to 5 metulae, clavate, 8 to 10^ long by 

 3 to 4/u in diameter, each bearing 2 to 4 sterigmata, smooth, up to 10/x long by 2.5 to 

 2.7m in diameter with short tubes; conidia globose, smooth, colorless, 2.3 to 2.7m in 

 diameter in long chains, often diverging; conidia showing connectives; sclerotia 

 numerous, black, mostly ellipsoid 400-800 x 300-500m with leathery to coriaceous wall 

 consisting of dark brown to greenish black polygonal cells. 



The species was isolated by J. C. Neill of New Zealand from the fruit body of a 

 Sclerotinia and was reported as C.B.S. 684. Its most striking character, as originally 

 described, was production of black sclerotia in great masses and in beautiful zones in 

 petri dish cultures. 



Our notes follow: 



Colonies on Czapek's solution agar growing rather restrictedly, about 

 2.0 to 2.5 cm. in 12 to 14 days at room temperature, irregularly furrowed, 

 loose-textured, floccose, white to light gray, bearing scattered conidial 

 structures within and upon a loose hyphal felt, in central colony area pro- 

 ducing abundant black sclerotia that may become quickly overgrown and 

 obscured by an aerial vegetative growth, occasionally showing sectors or 

 irregular areas with abundant sclerotia accompanied by a reduced or limited 

 mycelial development (fig. 167A); exudate limited, clear; odor lacking; re- 

 verse in dark greenish to black shades in areas of heavy sclerotial develop- 

 ment with marginal areas in the absence of sclerotia becoming dull to fairly 

 bright yellow to orange; sclerotia very irregular in form, usually elongate or 

 elliptical, often confluent, with long axes oriented along radial lines (fig, 

 167C) usually developing in the surface of the substratum, with dimensions 

 and texture as described above; conidial structures (figs. 167D and E) 

 with measurements as above, but with conidiophore walls less coarsely 

 roughened and with metulae usually in a single symmetrical verticil (as 

 figured by van Beyma). 



Colonies on steep agar spreading broadly, up to 5 or G cm. in 2 weeks, 

 radially furrowed, appearing loose-textured, 2 to 3 mm. deep, comparatively
